[Q] How do you delete bloatware via adb

Ive done this before and for the life of me i cannot remember how to do this, and ive been searching xda and google for a half hour now, can anybody help me out. How do you remove stock apps via adb?
Thanks guys

adb shell
$ su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# cd /system/app
# rm xxx.apk
Replace xxx with app names. Case sensitive.
Edit: ignore $ and # when typing the commands

Do I need to remove the odex files as well?
Sent from DynamikD's R00t3d & OC G2

Advisable to, yes. Also, reboot and clear cache in recovery for best results.

What is the command to list "dir" to get the app names? I've done this on my mytouch3g as well but rusty
Edit: It's "ls" lol.
Ok, so I just attempted this and get this error:
rm failed for Twitter.apk, Read-Only file system

And I also would like to remove these:
amazonmp3.apk

What is a .odex file?

Anyone know the name of the photobucket APK?

So now that we have Perma-ROOT, is it safe to delete these bloatwares without worrying about future OTA's?
And what's a .odex file? How do we delete this? Can we just delete these apps thru Titanium Backup and then boot into Recovery to clear cache?
*EDIT* - n/m i see how to delete the .odex files now

What's the .apk name for Photobucket?
*EDIT* - Got it... it's PbAndroid.apk

Need help!
Well those are the commands to remove a app how do you push a apk file back onto the /system/app. I want to push a Bluetooth.apk file from the old ROM to the new OTA and see if that helps with the Bluetooth issue I'm having with the new OTA.

If your perma rooted why not just install titanium backup and uninstall the app. If your temp rooted then you can only disable the app cuz if you delete the apps it'll only reappear after a reboot.

Becuz titanium does not let u remove apps, if it was that easy I think everyone would do it

how would the remount command change for the MyTouch4G?

Don't think it would.
BTW you can also try this remount command for either, I was advised that it's preferable to use and it's certainly easier:
mount -o remount, rw /system

[Q] Help needed

I just rooted my phone and i am trying to delete some of the apps that come with the phone.
I have found these steps in the forms but the problem is that, if I open a CMD and type this, it is not accepted.
I am guessing there is a step missing
1. type in the command line on your PC
Code:
adb shell
2. now you need to get super user rights:
Code:
su
3. you need to remount the system partition
Code:
mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
4. change to the /system/app directory and you can now rename/delete all files in there
I hope you make a copy of this folder, so you can always revert back to factory default. A hardreset doesn't restaure the deletet apps, so be carefull. Also you need to check on your own IF you can really delete a app or not. I don't know what features you use.

You can use root explorer, an apk that uses superuser permissions, or, maybe you didn't reboot the cellphone, when you root your, always reboot, in order to take the "effect"

try freezing app. Easier and safer. If you want to delete. Root explorer or try super manager.

Did you try with Titanium Backup ?, I think you can freeze, clear data and unninstall it !, let me know if I'm wrong

Download supermanager app from market. Enable root function. Get to phone dir. System then app

worked like a charm

after the 1 click root - not able to mount some directories in root explorer?

I used the post to install the one click root for the samsung epic 4g (sprint), and it appears to have worked. However - after entering root explorer, only some of the directories allow me to edit files. I click the remount as r/w button but nothing happens. Any thoughts?

Are you sure you granted root permissions to root explorer when it first ran? Run the superuser app from the app drawer and see if root explorer is on the list of apps that are allowed root permission.
I just tried v2.17.2 and it works fine. I tried changing the permissions on /system/xbin/busybox, it said filesystem mounted ro, then I press the mount rw button and redid the permission change, this time it worked no problem.

Thanks for your response-
yes, when i ran root explorer it asked if i wanted to grant superuser and i said yes. some folders allow it to remount, but - say the /system/bin folder - it doesnt allow it at all.

for further background, i used the automated instructions here for my root:
http://forum.xda-developers.com/showthread.php?t=1342728
i did option A like 5 times and also did option C (as i have EK02).
When opening root explorer it tells me that i have super user permissions. one thing to note- if i go to /system/xbin, i do not see a busybox directory. is there something else i should be installing?
in fact, i cant mount anything under the system directory or sub directories, but above that, i was able to change to r/w mode. i could also mount the /vendor directory right beside the /system directory...

If you were able to remount "/" as r/w then the problem isn't with root. That is basicly an "I'm a little bit pregnant situation" Either you are or you aren't.
Now if you weren't able to get root in the first place, then I'd look at the root.
As to busybox, there is no directory. There should be a file /system/xbin/busybox Also there should be a bunch of symlinks from various apps it supports to busybox.

I see - yea i did validate that busybox is not allowing for a mount or any type of change on that file/directory including busybox but the file is present. any suggestions on what else may be locking down this system directory?

I don't know if root file explorer is implemented it's own concept of ro/rw to protect you from making mistakes or it is using the system facilities. If it is using the system facilities, then once you remount /system as rw, then everything under /system is automatically rw. It is all the same partition.
I would try it from "adb shell" (do not type $ or # symbols)
Code:
$ su
# mount -o remount,rw /system /system
# cd /system/xbin
# chmod 755 busybox
If it lets you do that with no errors, then you have remounted /system/xbin as rw and the problem is with root file explorer. For that, you'd have to check with them or someone more well-versed in why that might be failing.

i appreciate your help
I went off googling the adb stuff/installed it and java's jdk stuff. then figured out how to run that adb shell stuff and validated that it worked (permissions were changed in places that this app didnt allow). knowing that the problem is actually with root explorer helps a ton.. as I just assumed it was working

[Q] Deleting system file in terminal causes reboot

Hello all,
I'm trying to delete a system file using the Android terminal (as my end goal is to put it in a run shell task in Tasker) and it either reboots my phone or just doesn't delete.
Long story short, I'm using the Weak Sauce root method, but I do not have S-Off as I like how easy it is to undo the Weak Sauce root alone. This means, of course, I don't have immediate RW access to system. So here's what I've done:
Code:
# mount -o rw,remount -t yaffs2 /dev/block/mmcblk0p46 /system
# busybox rm -f /system/media/audio/ui/camera_click.ogg
# mount -o ro,remount -t yaffs2 /dev/block/mmcblk0p46 /system
When I do the first and last commands alone, the system mounts as RW and RO correctly, confirmed with # mount|grep system. But that middle command is the problem. Sometimes nothing will happen, other times my phone will reboot. I've also tried adding the following before the rm command with no success:
Code:
# chmod 777 /system/media/audio/ui/camera_click.ogg
I AM able to delete the file manually through ES File Explorer when mounted RW. But it comes back after I restart my phone, hence why I want this command to be used in Tasker.
What am I doing wrong?
PS: as for the "why" of deleting the shutter sound file, I take screenshots sometimes and the sound drives me nuts. I've tried removing the ogg file from the camera apk, but that didn't work after a reboot. I also tried replacing the ogg file with a silent one, but no success there either as the real one reloads itself when I restart.

I'm trying to do it from the terminal so I can eventually put it into Tasker. I can delete it successfully with ES File Explorer, so no need for recovery. I just need some way to get it to work through the terminal.

If the file is coming back then you don't have proper write access to system and the file isn't actually being deleted which Is why it appears to come back.
Try using root explorer instead or do it through TWRP. Make system RW then just move or rename the file rather than delete it. If you have proper write access it will stick.

It comes back when you reboot. Your system is not writable you need to S-OFF. get system RW kernel, or delete through recovery.

Ah, that makes sense. What's the system RW kernel you mentioned? I'm not familiar with that.

[H] Can't make changes on System/usr/keylayout READ-ONLY

Hi guys :laugh:
I've successfully rooted my table, installed Supersu, TWRP and even tried the CM11 ROM in it.
The main problem is that I want to add/change some files on the /system/usr/keylayout folder so I can configure correctly my xbox 360 wireless controller (I'm having the spin buggy thing on some games).
But whenever I try to make changes in that folder using "ES File Manager" (granting it SU) It just pops up "Try again, this folder is read only"
I tried changing it through the Terminal Emulator through these steps:
su
cd /system/usr/keylayout/
mount -o remount,rw /system (or mount -o rw,remount /system its the same)
Didn't make any difference...
Can anyone help me really hard here?
Thanks guys :highfive: (and girls)
edit:
I'm now with the LG Firmware 50020D and android vers 4.4.2 (rooted)

up
anyone?

install ES File manager via Play store
You can activate Root browser in ES File manager. You need to click on the root browser settings within ES File manager, and mount /system/ as RW
